Specification forming part of Ldters Patent No. [51,531, dated June 2, 1874; application filed Manh 14, 1874.

To all whom it may concern Be it known that we, J ACOB P. BECK, JAMES F. SHOEMAKER, and J oHN HNVEAVER, ofLock Haven, in the county of Clinton and State of Pennsylvania, have invented a new and Improved Machine for Raising and Smoothing Panels, of which the following is a specification:

The invention will first be fully described, and then pointed out in the claim.

' Figure 1 is a plan view of our improved machine. Fig. 2 is a transverse section, taken on the line 00 a; of Fig. 1. Fig. 3 is a longitudinal sectional elevation.

Similar letters of reference indicate corresponding parts.

A represents the mandrel 5 B, the metal disk for one of the heads 5 O, the padcarrying disk; E, the pads; F, the sand-paper; G, a washer in front of disk B; H, another metal disk for another head; B, the pad-carrying disk 5 G, washer; I, clampingcollar; J, binding-nut; and K, cornering 0r grooving cutters, clamped between washers G G, for cornering or gr0ovoff to the shapes required.

ing out the edge of a panel at the same time that it is sandpapered. M represents the holes in the disks for the pads and the sand- ,paper. In case only one head is to be used, the collar 1 and binding-nut J will be screwed on against disk B, or the space may be filled out between. it and the collar by other washers. The pads whereon the sand paper is held will be made of wood, for turning them L is the table, on which the work is moved along to the heads.

Having thus described our invention, we claim as new and desire to secure by Letters Patent-- The combination, with one or more sandpaperin g-heads, of groovin g-cutters K, relatively arranged on a mandrel, as and for the purpose specified.
